I have done some testing and all seems to work as I would expect. Can you post some example code, so I/we can see what you are trying to do?

Have you tried recompiling your program(s)? Project>Compile All

Have you tried to install with apt install gb.gtk3.webview?

Are you developing on a different version of Gambas to the ones installed on the Debian machines?

You can easily test your original program by changing the Components with Projects>Properties>Components.

I have run Gambas programs on a touch screen with no issues. Try changing gb.gui to gb.gui.qt and see if that helps.

Very good!

That sounds better but be aware that the Ubuntu version of Gambas has its issues. I suggest you use the ppa to install Gambas. The following command will do it all for you. sudo add-apt-repository -y ppa:gambas-team/gambas3 && sudo apt-get update && sudo apt-get -y install gambas3
